The retina is a light-sensitive membrane at the back of the eye, When light passes through the eye, the lens focuses an image on your retina. The retina converts the image to signals that it sends to the brain through the optic nerve. The retina works with the cornea, lens, and other parts of your eye and brain to produce normal vision. Retinal detachment occurs when the retina separates from the back of the eye and can cause partial or total vision loss depending on how much of the retina is detached. When the retina becomes detached, its cells may be seriously deprived of oxygen. Retinal detachment is a medical emergency and it is advisable to consult your doctor immediately if you suffer any sudden vision changes.
Listen to Dr. Himanshu Mehta speak about Retinal Detachment and how technology at The Vission Eye Center can bring about complete, swift restoration of vision.
In most cases, surgery is necessary to repair a detached retina. For minor detachments or tears of the retina, a simple procedure may be done at The Vission Eye Center
If the retina is still attached but has a hole or tear, you may need to undergo a procedure called photocoagulation with a laser. The laser burns around the tear site and the resulting scarring fixes the retina to the back of your eye.
Another treatment option, called Cryopexy, is to apply a freezing probe outside your eye in the area over the retinal tear site, and the resulting scarring will help hold the retina in place.
A third option that works well in case of minor retinal detachments is Pneumatic Retinopexy. In this procedure, the doctor puts a gas bubble in the eye to help the retina move back into place up against the eye wall. Once the retina is back in place, a laser or freezing probe is used to seal the holes.
In case of severe retinal detachments, the recommended treatment is an eye surgery called scleral buckling. The procedure entails placing a band around the outside of the eye to push the wall of the eye into the retina and getting it back into place for healing. Scleral buckling is often done in combination with a Vitrectromy. Cryopexy or retinopexy is performed during the scleral buckle procedure.
Vitrectomy is usually carried out in case of larger tears. The procedure involves anaesthesia and is usually carried out as an outpatient procedure; in some patients an overnight stay at the hospital may be necessary. The doctor uses small tools to remove abnormal vascular or scar tissue and vitreous, gel-like fluid from the retina. Post this; the retina is put back into its proper place, most often, with a gas bubble. Cryopexy or Retinopexy is performed during the vitrectomy procedure.
